Ben Nemec d20754f6ed Use %i instead of %I in dhcp-interface@.service Per the bug report, %I results in -'s in the interface name being replaced with /'s, which means when we try to look up the interface by path in dhcp-all-interfaces.sh we end up at an invalid path. Using %i instead should fix the problem. See https://www.freedesktop.org/software/systemd/man/systemd.unit.html Essentially what is happening is that we start with a name like br-ex that wasn't escaped in the first place. However, because of the - it looks like it could have been escaped to systemd. When we use %I, which tries to unescape escaped values, it unescapes a value that was already not escaped.

===================
dhcp-all-interfaces
===================
Autodetect network interfaces during boot and configure them for DHCP

The rationale for this is that we are likely to require multiple
network interfaces for use cases such as baremetal and there is no way
to know ahead of time which one is which, so we will simply run a
DHCP client on all interfaces with real MAC addresses (except lo) that
are visible on the first boot.

On non-Gentoo based distributions the script
/usr/local/sbin/dhcp-all-interfaces.sh will be called early in each
boot and will scan available network interfaces and ensure they are
configured properly before networking services are started.

On Gentoo based distributions we will install the dhcpcd package and
ensure the service starts at boot.  This service automatically sets
up all interfaces found via dhcp and/or dhcpv6 (or SLAAC).
